Embargo functionality for DC19

[GoogleCodeExporter]

We need to add an embargo date to datasets. This could be e.g. an "embargoDate" 
attribute on the root <dataset> element.

The dataset xform would need a widget for editing the date (including the 
ability to remove it).

Then we need to check the embargo date when crosswalking the data to RIF-CS and 
Solr, and we need to implement access control on the Fedora record, too.

embargoDate has been added to <dataset>, relevant changes have been made to 
templates and xforms.

Determine the appropriate action to take with an embargoed record, add checks 
to relevant locations.

1. Ask Rob, et al. for guidance regarding embargoes
2. Add relevant checks for publishing datasets

Here's a simple method of implementing a date comparison lib in xslt:
